Tip & How-To about Computers & Internet
There are different ways in which a virus can spread from computer to
computer, but let's take a look at the most frequent ways in which
people run into viruses, spy ware and Trojans via the Internet.
Adult Websites: adult websites, gambling websites and other less than trustworthy websites will attempt to automatically access your computer when you visit them. They often install adware bugs that will cause a flurry of pop ups to appear on your screen. This adware will often allow for other programs with even more nefarious purposes to be installed and before you know it, your computer will be swamped. To stop these rogue websites, adjust the settings on your antivirus software and firewall so that no outside connections can be made and no programs can be installed without your express permission.
Email attachments:It has been discovered that since the advent of email attachment by Microsoft's Outlook Express.it is been used as medium by which viruses can be transferred from user to user. It is advised that if you don't know what an attachment is, don't open it. simply use common sense when opening attachments in your email.
Boot disk Infected :a virus can still be spread if an infected disk is in your hard drive and you attempt to restart. When you start your computer, your machine will always check your drives to see if a disk with boot information is present. If one is, your computer will likely automatically attempt to boot from the disk and not from your drive. If a virus is present in the boot disk, it will often be activated and you will become infected. Always know the origin of any disk you put into your drive.
Local Area Networks. If your computer is connected to a home network or if your work computer is part of a larger network, you may find yourself with an infection through no fault of your own. Someone else on the network downloaded a bug by accident, and within minutes, the entire network could be infected. There isn't much you can do to stop these kinds of infections, short of having your network administrator ensure that everyone's antivirus software is up to date so that the invading bug can be removed as quickly as possible.
Softwares. Downloading files or softwares from the internet can create an access to virus infection on you pc. The key here is to only download freeware or shareware from a trusted source like CNet that always ensures your safety.
Phishing : A phishing scheme starts when you receive an email from a website claiming to be your bank or credit card company, people end up with their identity stolen and a computer fill of viruses. Often times, when you visit these sites, spyware, adware and viruses are automatically installed on your computer The smartest thing you can do is to simply call your bank or credit card company if you receive an email saying there is a problem with your account instead of blindly following links in your email.
Chatting Messagers: These programs are often targets of hackers who see an easy way to trick people into clicking links that lead them to rogue websites. Common sense can keep you out of trouble, however. Only chat with people you know and never follow links to sites that you don't recognize. You should easily be able to keep Internet worms, viruses and other bugs at bay
Hackers. Today, people understand the value of good online protection, but hackers can still pose a problem if you allow your protection software to lapse. The best way to beat hackers is to ensure that you have a firewall and up to date antivirus software.
External Mobile Devices. There really is no way to stop such an infection from happening, since we all buy peripherals that work with our computer, but we can ensure that we have the tools ready to go if an infection should happen. Keep your anti virus software up to date at all times and you should be able to wrestle control back from any Internet bug.
Fake Anti Virus Software. This is one of the most frustrating ways to become infected with a virus or worm. There are dozens of anti virus and anti spyware programs you can download for free on the Internet and a surprising number of them actually do exactly the opposite of what they claim. The product websites make outrageous claims that their product can protect you from a whole range of threats, when, in reality, their product will only make things a thousand times worse. Only download antivirus programs from trusted sites or from websites that you know are completely legit.
When we know how spread, we can put an end to their reign of terror online. It is only with the right knowledge that Internet users everywhere can beat online bugs for good.
